JOHN KINEY UNDERIVOOD, OF LA MOURE, NORTH DAKOTA, ASSIGNOR' OF ONE-HALFTO JAMES IV. STODDARD.

SEED-PLANTER.

SPECIFICATION forming part of Letters Patent No. 461,153, dated October13, 1891.

Application filed June 24, 1891. Serial No.397,359. (No model.)

To all whom it may concern.-

Be it known that I, JOHN KINEY UNDER- WOOD, a citizen of the UnitedStates, residing at La Moure, in the county of La Moure and State ofNorth Dakota,have invented certain new and useful Improvements inSeed-Planters; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention has relation to revolving-disk seed-planters; and itconsists in the novel In the accompanying drawings, Figure l is a topelevation of my invention. Fig. 2 is a detail sectional view of therevolving disks and the frame which supports them. Fig. 3 is aperspective view of the hopper, showing the manner in which thedistributing-chain works. Fig.4 is a sectional view of the hopper,showing how the seed is allowed to flow out. Fig. 5 is a detail sideview of the rear arm a, and its attachments.

My invention is described as follows: It consists of a platform A,having the rearwardly-extending arm a. This platform is mounted on threesmall truck-wheels a a and a The forward trucks are journaled on anordinary axle a with the king-bolt a at the right of the centerof theplatform for the purpose of bringing the line of draft in the center ofthe cylinder of revolving disks.

On the platform A is secured a hook (i which extends down and enters theeye of on axle a thus holding said axle in a stationary position whenthe seeder is passing down a row. When the end of a row is reached, thehook a is removed from the eye a, and the seeder can be turned around inits own length. The rear end of the arm a is bent down, and to it ispivoted the landside a Said landside is made of hardened steel, and isbeveled at its frontend to pass over obstructions. The rear end of saidlandside is connected to the armaby means of a chain a Said landside hasalso the arm a", on which is journaled said rear wheel a the lower edgeof the landside being a trifle lower than the wheel, so that it willenter the ground. On the axle a near the wheel a on the right, is asimilar" landside a l l Along the rear side of the platformAis secured ahopper B, having the bottom I), (see Fig. 4,) provided with theperforations Z), and secured in said hopper is a sliding board 11 havingthe perforations 11 corresponding with the perforations b By means ofsaid sliding board the fiowof the seed is regulated. The sliding board bis operated by a lever b ,piv oted to the front side of said hopper andconnecting with said sliding board 11 through the slot b Said hopper hasjournaled in i'tthe two wheels 1) 12 which carry an endless belt orchain b The wheel I) is loosely journaled on its axle, while the Wheel12 is secured to its axle, which in turn is secured to the cog-wheel bon the outside of the hopper. The cog-wheel b meshes with the cog-wheelb set at right angles to said cog-Wheel b Said cog-wheel b is mounted ona shaft, which connects with the sprocket-wheel b,which is operated bythe sprocketchain h which passes around a sprocket-wheel b, secured tothe revolving shaft of the disk cylinder.

The shaft O,to which the disks are secured, is journaled in the boxes 0c, which are adapted to be drawn up .and down in the hollow uprights c cby means of the cable 0'. (See Fig. 2.) Said cable passes over theWindlass c on the top of the cross-piece a, connecting the two uprights,and is operated by the lever 0 Said lever is held in the desiredposition by the pawl c engaging the ratchets of the stationary wheel 0The cable may be lengthened or shortened by the turn-buckle 0 (See Fig.1.) The disks 0 are secured to the shaft O, andextending down from theattachment c ,secured to the cross-piece 0 are the cleaners 0 which keepthe disks free from brush and like obstructions.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. A seed-planter consisting of the platform A, having therearwardly-e'xtending arm a, axle a pivoted near the right-hand side ofsaid platform, having the eye a andlandside a hook at, securing theleft-hand end of said axle, landside a pivoted to the end of arm a, andhaving the arm a, chain a connecting the rear end of said landside andarm a,hopper B, having the perforatedbottom b and perforated slidingboard 17 adapted to be operated by the lever b Wheels 29 and b oarryingendless chain b cog-Wheels b and b sprocket-Wheel b, and sprocket-chainI9 shaft 0, having the sprocket-Wheel Z9 and disks a", movable boxes 0,hollow uprights o cross-piece 0 cable or, Windlass c and lever 0substantially as shown and described.

2. In a seed-planter, the platform A, axle a having the eye a andpivoted under said platform near its right-hand side, and hook 11 I 5secured to said platform andadapted to hold the left-hand end of saidaxle, substantially as shown and described.

In testimony whereof I affix my signature in presence of two Witnesses.

JOHN KINEY UNDERWOOD.
